The short answer. If you want another lease and sale comps database, Moody's CRE comes closest to CompStak on our scoring of vendor sites, followed by MSCI Real Capital Analytics; for multifamily rents, HelloData and Radix. If you need comps only for the deals in front of you rather than a subscription, Titleman builds a comp set for one address in about 19 minutes at the median, flags the rows that are not comparable and says why, but it is not a database you browse.

Written by the Titleman team with AI assistance (Claude). Every description of another company is that company's own wording or a summary of its own site, read on 19 October 2026 and linked; we have not run those products. Titleman figures are medians measured on our production runs in the 30 days to 18 October 2026.
What CompStak Is (October 2026)
CompStak describes itself as "commercial real estate data, straight from the source". On its own pages:
- Lease comps with starting rent, net effective rent, free rent, tenant improvements and escalations.
- Sale comps with cap rate, NOI, buyer and seller and price per square foot, plus property data and loan data such as lender, loan to value and maturity.
- Exchange, a give-to-get model: "trade the comps you have for the comps you need." You submit comps to earn credits and spend them to unlock others, and analysts check each submission.
- CompStak One and One Connect for enterprise users, with an AI market summary, natural-language comp search, an MCP server for AI assistants, and a Rent Predictor that, by CompStak's description, covers office and industrial space.
- Coverage stated as 105 US markets and more than 40,000 contributors.
Exchange is described as free for brokers, appraisers and researchers who contribute; we found no published price for the enterprise products.
Why Teams Look For A CompStak Alternative
- No comps to trade. Exchange access depends on contributing. Owners, lenders and investors often have few lease comps to give.
- Multifamily rents. CompStak's Rent Predictor is described for office and industrial, so apartment teams look elsewhere.
- Transactions and capital flows, not lease terms: who bought, who financed, at what pricing, across countries.
- A market outside the covered list, or a property type where the comps are thin.
- Comps for one deal, not a subscription. Some teams need a defensible comp set ten times a year, not a database every day.
The first four are data jobs, and the data platforms below do them. The fifth is where Titleman fits.

How We Scored Them
Each tool gets 0, 1 or 2 points on four criteria, based only on what its maker's site describes: 2 means described as a core part of the product, 1 means partial or for a narrower case, 0 means not described. Lease comps count double, because lease comps are what CompStak is best known for. Ties are listed alphabetically.
| Tool | Lease comps (x2) | Sale comps | Coverage stated | Delivery into your tools | Score of 10 |
|---|---|---|---|---|---|
| Moody's CRE | 4 | 2 | 2 | 2 | 10 |

This is a reading of each vendor's own description against the CompStak job, not a test of their data. Data quality in your submarket is the thing that decides, and no table can show it.
The Seven Alternatives
1. Moody's CRE
Moody's describes the Moody's CRE platform, formerly REIS, as "a top-tier, comprehensive CRE data intelligence platform". It lists more than 8 million US properties, 275+ markets and 3,000 submarkets, asking and effective rents, vacancy and absorption, sale comps and lease comps, true-owner contacts, forecasts, and a similarity score for grouping comparable properties, with bulk data and API delivery. Best for teams that want lease comps, sale comps and market fundamentals from one vendor.
2. MSCI Real Capital Analytics
MSCI describes RCA as "an industry-leading global database of commercial properties, transactions and participants": transactions with pricing, loan data and ownership history, investor and lender profiles, and trends such as cap rates and capital flows across more than 170 countries. Best for institutional teams who need to know who is buying and financing, and at what pricing.
3. HelloData
HelloData's own line is "Multifamily Market Analysis: Automated": automated rent comps and market surveys, unit-level rents and concessions, weekly leasing activity, expense and NOI benchmarks, a rent roll parser and an API. Best for apartment managers, developers and acquisitions teams.
4. Radix
Radix says you can "master the market with the leading AI multifamily platform", with analytics, underwriting and intelligence across comps, units and market signals, and connections to Excel and BI tools. Best for multifamily owners and operators who benchmark a portfolio.
5. Titleman
Titleman is not a comps database, and it scores lower than the data platforms on coverage for that reason. What it does is build the comp set for the deal in front of you. For one address it returns, by default:
- sales of the same property type, within one mile (up to ten) and from the last 24 months;
- at least three priced comps before it calls the set enough, with the subject's own sale excluded;
- rows that are not comparable returned as "reference only", with the reason, and multi-parcel deeds flagged;
- the same rows in the same order when you send the same request again.
Measured on our production runs (30 days to 18 October 2026), a comps run with its workbook takes about 19 minutes at the median and returns about 460 data points. A market rent run for one property takes about 16 minutes. Runs draw on 2,100+ connected sources, and coverage depends on the county. Best for investors, lenders and brokers who need a checkable comp set per deal rather than a subscription.
6. Green Street
Green Street's site leads with "Insight becomes action in seconds with GreenStreetAI", and describes detailed private-market comps, forecasts and fundamentals, REIT analytics and a property price index, delivered through Excel, Snowflake, an API and an MCP server. Best for institutional research teams.
7. Yardi Matrix
Yardi describes Yardi Matrix as "the industry's most comprehensive market intelligence platform for equity investors, lenders and property managers", covering multifamily, office, industrial, self storage and other types across 150+ markets, with office lease and listing comps. Best for teams that want property-level market intelligence, especially if they already use Yardi.
How To Test A Comps Alternative
Take a deal you closed in the last year and ask each tool for comps on it.
- Did the subject's own sale come back as a comp? It should not.
- Are any rows listings that never traded? An asking price is not a comp.
- Is each comp the same property type and a sensible distance away? Count the ones you would throw out.
- For lease comps, is the rent net effective or face? Free rent and TI change the answer.
- Ask twice. Does the same request return the same set?

FAQ
What are the best CompStak alternatives in 2026?
For a lease and sale comps database, Moody's CRE scores highest on our reading of vendor sites, followed by MSCI Real Capital Analytics. For multifamily rents, HelloData and Radix. If you need comps only for the deals in front of you rather than a subscription, Titleman builds a comp set for one address in about 19 minutes at the median.
Is there a free alternative to CompStak?
CompStak's own Exchange is free if you contribute comps: its site describes it as trading the comps you have for the comps you need. The other data platforms on this page do not publish a free plan for their comps.
Can AI pull comps for a deal I am screening without a data subscription?
Yes, for one deal at a time. Titleman returns sales of the same property type, by default within a mile and from the last 24 months, in about 19 minutes at the median, and flags rows that are not comparable with the reason. It is not a database you browse: you ask for an address and get the comp set for that address.
Which CompStak alternative is best for multifamily rent comps?
On their own sites, HelloData describes automated multifamily rent comps and market surveys with unit-level rents and concessions, and Radix describes an AI multifamily platform with a view of every comp, unit and market signal. CompStak's Rent Predictor, by its own description, covers office and industrial space.
What is the difference between lease comps and sale comps?
A lease comp records the terms of a signed lease: starting rent, free rent, tenant improvements, term and escalations. A sale comp records a closed transaction: price, size, price per square foot and, where known, cap rate and NOI. Lease comps tell you what the income can be; sale comps tell you what buyers paid for income like it.
